Patented Feb. 1, 1916.

Application illed February 8, 1815. Serial No. 7,049.

To all whom it may concern:

Be it known that I, WILLIAM T. PEYTON, a citizen of the United States, residing at Weiser, in the county of \Vashingt-on and State of Idaho, have invented new and useful Im rovements in Spring-Tires, of which the fol owing is a specification.

This invention relates to spring tires and more particularly to an ad ustable means for securing the tire to a rim.

An object of the invention is to construct the tire of resilient wire having ortions thereof flat so as to allow for the di ereuces in size between the inner periphery of the tire and the outer eriphery.

Another object 0 the invention is the provision of a tire wherein the adjustable means thereof for securing the tire to the rim can be operated exteriorly with respect to the interior of the tire.

The invention consists in the features of construction, combination, and arrangement of parts, hereinafter fully described and claimed, reference being had to the accompanying drawings, in which:

Figure 1 is a fragmentary side elevation of the tire showing it a plied to the rim of a wheel. Fig. 2 IS a longitudinal section therethrough. Fig. 3 is a detail top plan view of a portion thereof. Fig. 4 is a cross section.

Referrin to the drawing, the numeral 1 designates t e rim of the tire having formed therein a peripheral groove 2 in which seats a portion of a tire member 3 formed of resihent wire flattened at intervals so asto provide a substantially inclosed tread portion. Contactin with the inner surface of that portion 0 the tire member that seats in the groove is a band 4 having a convex under surface 5 so as to tightly engage the convex inner surfaceof the tire member. The ends of the band are spaced a slight distance apart and as shown are connected by a. yoke ation to one end of the band, the remaining end being adjustable with respect to the remaining en of the band. That extremity that passes through the movable extremity of the yoke is screw threaded so as to cooperate with the threaded bore of a nut 7 that has its outer surface provided with a worm thread 8 cooperating with the worm 9 formed upon a shaft 10. One extremity of the shaft 10 rojects exteriorly of the rim and as shown, 18 squared so that an instrument can take hold for rotating the shaft.

From the foregoing description, it will be seen that a tire can be readily set into place and thus subsequently tightened by manipulatin the shaft 9 that in turn 0 erates the nut. or drawing the ends of the and closer together.

What is claimed is A spring tire comprising in combination with a grooved rim, a tire member formed of a coi spring having a portion seated in the groove, an annular band engaging the inner surface of that portion of the tire which seats in said groove, a yoke havin one extremity'fixed to one end of said ban and its remaining extremity adjustable with respect to the remaining end of said band, a. nut adjustably mounted on one end of said band and on aging the adjustable end of said yoke, an a worm shaft passing radially through said rim and having a squared portion arranged exteriorly thereof and further rojection through said yoke and cooperat- In with said nut whereby the latter may be ad usted upon the end of said band, said yoke frictionally engaging said nut at all times and forming a support for said shaft.

In testimon whereof I afiix my signature in presence 0 two witnesses.
